Had a couple of spare crankcase petcocks and retrofitted them based on Steve's vinyl tube sight gauge. I wanted a more secure attachment for the flexible tubing.
The 1/4" brass barbed fitting was cut from a standard adapter available at any hardware store. I drilled the petcock opening a little larger and filed the end of the brass fitting ... then soldered it in place.
Looks good and secure. Post an installed image too.
Going to winterize the T this weekend with anti-freeze and light weight oil. Will install these after draining the oil and will take a picture after I put in the fresh oil.
